Question 1

What happens when main bearings wear out?

Accepted Answer

Worn main bearings increase the clearance between the crankshaft and engine block. This causes a drop in oil pressure, which can damage other engine components due to lack of lubrication. Replacing the bearings restores proper oil pressure and protects your engine.

Question 2

How do I know if my main bearings are worn?

Accepted Answer

Common symptoms include low oil pressure, especially when the engine is warm. You might also hear a knocking or rumbling sound from the engine, which gets louder as the engine speed increases. An oil analysis can also reveal elevated levels of bearing material in the oil.

Question 3

What size are these bearings?

Accepted Answer

This ACL Main Bearing Set is 0.010 inch oversize. This means they are designed for crankshafts that have been ground down 0.010 inch during a rebuild. Using the correct size bearing is critical for maintaining proper oil clearance.
